Abstract

It is intended to provide a ferrite heat resistant steel excellent in solvent cracking resistance and creep strength in the HAZ. A high-Cr-containing ferrite heat resistant steel, characterized by containing (in terms of percent by mass) Si: not less than 0.1% and 1.0% or less, Mn: 2.0% or less, Co: 1 to 8%, Cr: 7 to 13%, V: 0.05 to 0.4%, Nb: 0.01 to 0.09%, either one of or the total of both of Mo and W: 0.5 to 4%, B: 0.005 to 0.025%, Al: 0.03% or less and N: 0.003 to 0.06%, and further containing C in an amount that satisfies the following formula (1), and Fe and impurities as remainders, wherein as the impurities, O, P and S are contained in an amount of 0.02% or less, 0.03% or less, and 0.02% or less, respectively. 0.005 ≤ C ≤ (-5/3) × B + 0.085 (1) In the formula, C and B represent the contents (% by mass) of the respective elements. Further, it may contain one element or two or more elements of Nd, Ta, Ca and Mg.
